Is my equipment messed up!? D90 with 18-55VR kit lens at 10 second exposure. I took a lot of pictures last night and only saw it on this pic. However, I saw it on a number of them the night before last. Is something messed up? or is it some kind of crap bouncing off of the combo of water and light? The other night when I saw them there was also water and lights. THANK YOU for replying im kind of freaking out about this right now. I don't have money for repairs!
